Brozz Swingarm Upgrade??

[PeaceSportsAtlanta]

Forgot I had the part listed on our website and someone ordered it so I had to open a new bike and yank the swingarm off it. I deleted the part from the website until I have more, which should be at the start of August.


Not sure if it'll fit on other China bikes but here are the measurements. See pics. This is for the blue eagle version. Standard has some slight differences due to the rear drum brakes. The bolt for the front of the arm and the axle are the same bolt and nut.

It was me. The most notorious parts buyer/experimenter here.

Not sure how much of an upgrade it will be, but I am mainly after the different adjuster style. You didn't have to pull the parts from another bike though. I would have been just as happy waiting for it. Pretty sure I need the rear axle for the wheel too due to length reasons, so I ordered that today.

I know. You just couldn't resist. The adjuster themself will be an improvement. Swing arm does look like it's stronger.

I can't help it. I see shiny things and I just have to have them.

The adjusters are a better design IMHO, and hopefully the adjustment markings are a little more accurate.

As far as strength, maybe. I have a feeling the thickness is close to the same. The tubing being capped off with the adjuster sections creating a shorter tubing length and bracing the end of said tubing should add some rigidity to it.

You know I was looking at the new kaw. klx230 and was thinking maybe their suspension or at least the rear shock might work on these bikes. The swing arm looks way cheaper then the china bikes though.

looking at the build quality of that arm it is very
hard to imagine how it could be a up grade on anything..

I thought the Bashan had an ali swing arm?
This looks like still steel? Or am I blind

That was my thought. Looks like a fabricated steel arm to me as well, so as I said, I don't think it will be much of an upgrade in terms of strength, unless they used thicker steel. It can't be any worse than the Hawk unit, especially on the adjuster end. We will know for sure once it arrives and I can compare it with the Hawk unit. If there is any increase in strength it would be due to the reasons I stated previously.

All of that said, it is an upgrade in adjuster style (personal opinion) and if the two ends of the arms are actually square with one another that would also be an improvement. For the price, it's hard to complain too much.

I plan on doing a side by side comparison of the two once I have it in hand. At least with this style I can't crush the end of the swing arm by tightening the axle down.

As far as I know the Brozz swing arm has always been steel, just painted a silver that looks like Aluminum. It could be possible that an older version sold with one, but most every one I have seen has looked like this.

Just checked my swingarm on my Brozz and a magnet sticks to it so it's definitely steel.

I sure thought that looked like shitty alum. The wields look horrible, shit even one side looks off by a 8th of inch. Ive seen posts that say this swing arm is alum. LOL. Funny how a little bit of paint can fool so many.



Question it looks like a simple item. WHat would a fab shop charge to do one in alum.? If chinese 10yr olds can weld up these surely a fab shop could make one pretty reasonable and better.



Question on suspensions does anyone actually know what size USD forks is on the brozz and the actual rear shock size? In all of these posts no one ever quotes a damn actual spec of what is on the bike, just what they say they changed to. Plus none of the dealers even list sizes. DO they not know or just choose not to list the sizes? I suspect they dont know.LOL Hell even on the csc site they dont list any exact sizes. Unbelievable.

I don't want to sound rude, but that swingarms, looks like a downgrade more than a upgrade.

The welds are honestly no prettier than most of the welds I have seen on the frames of any of these bikes. As long as they are structurally sound, then how they look is secondary. A strong weld doesn't have to be a pretty weld.

How much would a fab shop charge to replicate this arm in aluminum? Easily a few hundred dollars. It would be much cheaper to find a donor arm from a Honda model like an old XR or CRF and have a shop fab up and weld a shock mount on to the top of the cross brace to copy the original design. Or have tabs welded to the frame in order to use the Honda shock and linkage for their progressive setup.

I do agree that some suspension specs would be nice to record. There aren't that many active Brozz memebers on here, and even less of them are as into modification.

Not rude at all, just your opinion. It would really depend on what you are after and what you started with. In my eyes it is an upgrade in the adjuster style. Otherwise, probably not much difference there.

I just received the swing arm today. A quick look over it does reveal some positives in the design over the rectangular tubing of the Hawk that would give it a slight edge in rigidity. There was at least one or two things that were a slight disappointment as well, but I guess that is to be expected.
I wont have the time to test fit it today and I am waiting for the axle to arrive. I should be able to try and test fit it next Friday. I may make a small video later today going over it and trying to show some more detail.

Made in China 2019 and no one knows or says (nearly every bike or everything in life), THAT always is the case.
No it wasn't a 10 year old welding it but a grown man with a brain of a 10 year old (ask me how I know! I see it daily)
